Application January 13, 1947, Serial No. 721,752

This invention relates to a means for steaming and thereby shrinking umbrella covers which are mounted on the frames.

An object of this invention is to provide a steam injecting means which is adapted to direct steam against the lower side of an open umbrella so as to thoroughly moisten the cover and shrink the cover on the open frame so that the cover will be tight on the frame.

Another object of this invention is to provide an umbrella steaming device of this kind which includes means for supporting the frame so that the open umbrella will be properly positioned relative to the nozzle structure and can be easily and quickly mounted and removed.

A further object of this invention is to provide a steaming device of this kind which is simple in construction and is designed to evenly distribute the steam beneath and inside the open umbrella.

With the above and other objects in View, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a top plan view of an umbrella steamer constructed according to an embodiment of this invention,

Figure 2 is a sectional view taken substantially on line 22 of Figure 1,

Figure 3 is a detail side elevation of the device with the umbrella in section,

Figure 4 is a fragmentary sectional view taken on the line l--4 of Figure 1,

Figure 5 is a bottom plan view of the device,

Figure 6 is a fragmentary sectional view taken on line 66 of Figure 5.

Referring to the drawings, the numeral l designates generally a supporting stand which is formed of upright legs ll connected together at their upper ends by upper top forming bars l2. A transversely extending plate I 3 extends between one pair of the top forming bars l2 and forms a support for the umbrella stick holder as will be hereinafter described.

The stand in has mounted on the top thereof a steam ejecting head generally designated as it. The head I 4 .is formed of a pair of concentric spaced frustro-conical walls l and it, connected together by upper and lower walls I! and I8 respectively. The wall It is the outer wall and is formed with a plurality of steam discharge openings l9. The bottom wall l8 has secured thereto a plurality of circumferentially spaced apart 2 Claims. (Cl. 68-6) nipples 20 to which are adapted to be connected steam conducting pipes 2!, each having a valve 22 interposed therein. Ihe steam ejecting head M also has extending downwardly from the bottom wall i8 a drain nipple 23 with which a drain pipe 24 is connected and a drain valve 25 is interposed in the drain pipe 24. In this manner the condensate in the head 54 may be periodically drained therefrom. The stand ID has extending upwardly from the plate [3 thereof an umbrella holder which includes a tubular member 26 which is open at the upper and lower ends thereof and is formed at its upper end with a funnel shaped umbrella supporting member 21.

The stick 28 of the umbrella is adapted to be extended downwardly through the tubular member 28 and the bracin members 29 of the umbrella are adapted to rest on the upper large end of the supporting membe 21. The umbrella which is generally designated as 3D is disposed in open position over the head M, as shown in Figures 2 and 3, with the outer portion or marginal portion of the umbrella cover engaging over the head i i. In this manner the steam which is discharged through the openings or jets l9 will be directed against the outer portion of the umbrella cover and this steam will then move upwardly and inwardly to moisten the inner portion of the cover. In this manner the cover will be moistened to the desired degree for shrinking the cover on the frame so that when the frame is in open position the umbrella cover will be tightly stretched.

While I have shown the steaming head M as being of frustro-conical configuration, it will be understood that this head may be of angular configuration if desired, and of a size such that the cover of the umbrella will be supported in slight spaced relation to the steam jets which are formed in the steaming head.

In the use and operation of this device, the umbrella 39 is disposed in open position with the stick 28 extended downwardly through the tubular member 26 and the braces 29 for the ribs resting on the upper flared end of the funnelshaped support 2'5. The valves 22 may then be opened so that steam will be ejected through the jet openings is against the under side of the umbrella cover.

With a device as hereinbefore described, the

I do not mean to confine myself to the exact details of construction herein disclosed but claim all variations falling within the purview of the appended claims.

What I claim is: 5

1. An umbrella steaming unit comprising a stand, a centrally disposed upwardly opening tu bular support carried by said stand adapted to receive the stick of an umbrella, a steam supply main, a steam ejector carried by said stand about 1 said support and connected to said main at circumferentially spaced points, said steam ejector comprising a hollow frusto-conical body having downwardly divergent side walls, said walls formed with upwardly and outwardly opening steam discharge openings for discharging steam against the under side of the umbrella, and a funnel shaped membe carried by said support with which the rib braces of the umbrella are engageable for supporting the open umbrella on n said unit.

2. An umbrella steaming device comprising a frusto-conical steam ejector, spaced inner and REFERENCES CITED The following references are of record in the file of this patent:
